Abstract

In this study, a vacuum-assisted resin transfer molding system was designed to enhance the conventional fabrication process of m acro-fiber composites (MFC) by replacing non-recyclable epoxy with the biodegradable and eco-friendly thermoplastic resin, Poly L-Lactide co ε-Caprolactone (PLCL). The polymerized PLCL was analyzed for thermal properties using differential scanning calorimetry; the results indicated a crystallinity of 7.51%. The morphology of the polymer-impregnated macro-fibers was examined through scanning electron microscopy, confirming uniform fiber impregnation without the presence of voids. To assess sensor performance, a 5 V voltage was applied through a signal generator, and an oscilloscope was used for measurement. The sensitivity of the half-cut PZT MFC was observed to be greater compared to that of the thru-cut PZT MFC. Additionally, vibration tests verified that the fabricated MFC effectively functioned as a sensor.
